It seems like just yesterday when we were talking about how Topsy was doing Google+ search better than Google, as the company announced realtime (and other) Google+ search results. As a matter of fact, it was yesterday.

Now, Google has announced real-time search for Google+. How about that?

“Now when you search in Google+, you’ll see a message about new posts the instant they’re available,” SVP, Engineering Vic Gundotra says in a Google+ update. “If you click on this message, or select ‘Most recent’, then relevant posts will start appearing in real-time.”

Now, I wonder when we’ll see this come back to Google search.

Google+ also now has improved hashtag support. “People have long used hashtags to mark their posts with certain topics — just ask our very own +Chris Messina, hashtag inventor. You don’t have to use hashtags on Google+ (search works fine without them), but when you do, we’ll automatically link to search results.”

Based on the feedback on Gundotra’s post, users are pretty fired up about the hashtags.

Google said it would bring realtime search back to Google search (it went away after Google lost Twitter firehose access) with data from Google+ and other sources, but that’s not part of today’s announcement. Perhaps, they’re letting the user base grow more first.
